This looks like ACPI bug...
Nouveau calls this method:
Method (_ROM, 2, NotSerialized)// _ROM: Read-Only Memory
{
Add (Arg0, RBUF, Local0)
ShiftLeft (Arg1, 0x03, Local1)
Name (VBUF, Buffer (Arg1) {})
OperationRegion (VROM, SystemMemory, Local0, Local1)
Field (VROM, ByteAcc, NoLock, Preserve)
{
ROMI, 65536
}
Store (ROMI, VBUF)
Return (VBUF)
}
with Arg0 == 0, Arg1 == 3 and gets:
ACPI Error: Field [ROMI] Base+Offset+Width 0+24+1 is beyond end of region [VROM] (length 24) (20120913/exfldio-210)
ACPI Error: Method parse/execution failed [\_SB_.PCI0.PEGR.GFX0._ROM] (Node ffff88033e47fe88), AE_AML_REGION_LIMIT (20120913/psparse-536)
We can workaround it by aligning Arg1 to 4096 (I'm wondering what is the minimal
value), but do we really have to?
